VCID-8977-tjss-w7ba
Aliases: CVE-2021-45046 GHSA-7rjr-3q55-vv33 |
Incomplete fix for Apache Log4j vulnerability The fix to address [CVE-2021-44228](https://nvd.nist.gov/vuln/detail/CVE-2021-44228) in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allow attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in a remote code execution (RCE) attack. |

Aliases: CVE-2020-9488 GHSA-vwqq-5vrc-xw9h |
Improper validation of certificate with host mismatch in Apache Log4j SMTP appender prior to version 2.13.2. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. |

| VCID-jwav-88m7-6fhz | Remote code injection in Log4j Log4j versions prior to 2.16.0 are subject to a remote code execution vulnerability via the ldap JNDI parser. As per [Apache's Log4j security guide](https://logging.apache.org/log4j/2.x/security.html): Apache Log4j2 <=2.14.1 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.16.0, this behavior has been disabled by default. Log4j version 2.15.0 contained an earlier fix for the vulnerability, but that patch did not disable attacker-controlled JNDI lookups in all situations. For more information, see the `Updated advice for version 2.16.0` section of this advisory. |
